Couldn’t find meta-data for provider with authority

First, write the following tag in manifest under the <application> tag

 <provider
            android:name="androidx.core.content.FileProvider"
            android:authorities="${applicationId}.provider"
            android:exported="false"
            android:grantUriPermissions="true">
            <meta-data
                android:name="android.support.FILE_PROVIDER_PATHS"
                android:resource="@xml/provider_paths" />
        </provider>

Then create a xml folder in res and create a file named: provider_paths.xml
and then copy paste the code:

<?xml version="1.0" encoding="utf-8"?>
<paths xmlns:android="http://schemas.android.com/apk/res/android">
    <external-path
        name="external_files"
        path="." />
</paths>

And now here’s where most developers make mistakes: in your script, create your File with:

FileProvider.getUriForFile(Objects.requireNonNull(getApplicationContext()),
                    BuildConfig.APPLICATION_ID + ".provider", file);
